Tracheal Reconstruction Surgery Supported by Extracorporeal Membrane Oxygenation for Patients with Traumatic Post-tracheotomy Tracheal Stenosis.

PURPOSES Patients who require surgeries for traumatic post-tracheotomy tracheal stenosis (PTTS) often cannot be supported using conventional airway management approaches. This study documents the use of extracorporeal membrane oxygenation (ECMO) in patients with PTTS. METHODS Patient characteristics, procedure, and outcome of patients who required tracheal reconstruction surgery for PTTS supported by ECMO were retrieved and analyzed. RESULTS Four patients (mean age 28 years; range 17-48 years) with traumatic PTTS underwent tracheal reconstruction surgery supported by ECMO. The mean time from removal of tracheotomy tube to admission was 3.2 months (range: 1-9 months). The mean diameter of the stenotic segment was 5 mm (range: 4-6 mm). One patient underwent tracheoplasty and semi-tracheostomy with venoarterial ECMO urgently. Three patients underwent tracheal resection and end-to-end anastomosis (TRE) with venovenous ECMO empirically. Intervention success was achieved in 100% (4/4) of patients. The mean duration of ECMO was 35.3 hours (range: 16-53 hours). The overall survival rate was 100% (4/4) within a mean follow-up of 26 months (range: 7-57 months). CONCLUSIONS ECMO is a safe and feasible method to support oxygenation for patients with critical traumatic PTTS during tracheal reconstruction surgery.
